When the scalp lacks moisture, it causes the hair to weaken therefore hydrating treatments are extremely important for the overall scalp health. Most people tend to associate moisture with oil or vice versa, so most tend to think that moisture is not needed when the scalp is oily. People with oily scalp usually lack moisture due to the strong products they use to remove excess sebum.
These products tend to strip away moisture in the process of deep cleansing the scalp. Once the scalp lacks moisture, it loses its biological equilibrium, making it taut and affecting blood and nutrients circulation. The same happens on the hair, making it susceptible to damage which weakens the hair shaft.
